OpenGL Double Buffering

Hi,

I'm having a problem with OpenGL double buffering. I'm using JOGL so I'm not sure if this is a general OpenGL question or a JOGL one!

I'm noticing that when I move objects around I can sometimes see the scan lines being rapidly drawn. There is no flickering as such, as i think i have double buffering on. I set double buffering in 2 places. Once in the capabilities (capabilities.setDoubleBuffered(true)), and once in the initialisation (glEnable(gl.GL_DOUBLEBUFFER)). Are these the only 2 things you need to set for double buffering? I've noticed some code using a swapbuffers function, is this something thats needed?

Any ideas why I'm sometimes seeing these scanlines being rapidly drawn?

Kind Regards,
Michael

Are you embedding JOGL into a Swing app using GLJPanel?  Or doing a standalone OpenGL app with no GUI elements?

Yes I'm using swing elements and I'm adding the GLCanvas it to a standard JPanel. Could a GLJPanel be the answer? I've never heard if it before! :)

Thanks for all of your input. I really think this is a JOGL issue. I'm not sticking with Java for too much longer so i hope i wont be plagued with this problem in the future!

Thanks again!
